Up vision + agility to soft cap.
Get confidence into the 30's.
Then get some SAs, either go Full O-Line, Full Pancake or a Mix of the two.
Run/Pass Block are god SAs, SHOCK BLOCK is a fantastic SA when you are faced against much faster players. O-Line is very under rated, it gives a whole boost to the line which can be useful.
If it was me, I'd train:
Vision+Confidence on intense.
Work on getting agility to 48.
Get Pancake up to 5.
Then focus on O-Line and Shock Block.
(That's the route I plan to go with my C.)
